One week review:
I don't have much to compare as this is my first Vette.
The ZR1s that I replaced were the originals and the front tires had cords showing on the inner tread. The rears were fine but since they were 18 years old they be gone. They had 25,000 miles on them.
I decided to purchase a compatible sized tire as I wasn't able to locate other brands of tires with the exact OEM size.
Initial thoughts on the Continentals:
Looks: I prefer the looks of the ZR1's. IMO just look more aggressive. Flat sidewall compared to the 'slight bulge' of the Continentals.
Drive: Much more compliant. Smoother and quieter.
Traction: I've driven them in rain, heavy rain, and dry weather. Felt very confident in all.
Handling: A bit of a difference compared to the ZR1s, but I am not an aggressive driver so no biggie.
The car seems to rock from front to back if I get on slightly bumpy roads now that I have the Continentals on. This may be an indication of needing new shocks. I am looking to replace them with the C6 shocks.
Purchased from my local Discount Tire franchise and was impressed with the quality and speed of service. They were aware and had the necessary pucks to lift the vehicle. I have permanent pucks so no issues there. The jacked up the vehicle with 4 jacks which kind of surprised me.
FYI: Discount Tire only offers a 25,000 mile warranty on these 50,000 mile tires. They state this is from the manufacturer due to the tires not being able to be rotated.
I will be looking to get an alignment soon.
